GUY-ANCHOR.

To all whom it may concern.

Be it known that I, F nno N. Blnnon, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Guy-Anchors, of which the following is a specification.

My invention relates to improved means for anchoring guy wires for poles, smoke stacks or other objects to the ground which are held in position by guy wires or lines.

The object of my invention is to provide an anchor having a minimum amount of metal necessary to secure efficient results and yet which possesses adequate strength and resisting qualities for the purposes intend-ed.

Other objects and advantages are secured as will fully appear herein.

My invention consists in the details of construction and arrangement as herein set forth and claimed.

In the drawing which serves to illustrate my invention: Figure 1 is a vertical section through the anchor showing a rod secured thereto by a nut. Fig. 2 is a sectional view showing the anchor embedded in the earth with a suitable rod attached thereto, and Fig. 3 is a bottom view of the anchor.

In the embodiment of my invention as illustrated, and which shows a preferred construction, 1 represents a frusto-conical body provided with a round opening 2 in the top thereof and having an angular tapering hole or socket 3 below and adjacent said opening 2. A rod 4- having an eye 5 upon its upper end and a thread 6 upon its lower end is adapted to be inserted in said opening 2 and to be adjustably and detachably secured to said anchor by a nut 7. The socket is preferably tapered to permit the use of nuts of varying sizes as may be desired and the bolt is preferably threaded over a considerable portion of its lower end to permit of a wide range of adjustment of the bolt in relation to the anchor or shell 1. The shell being hollow permits free movement of the lower end the eye bolt within the anchor. The shell is provided with a series of preferably annular corrugations 8 formed of ridges 9 and grooves 10 respectively opposite each other on the respective surfaces of said shell. The shell is preferably tapered at an angle of about 45 degrees and preferably becomes thinner from the top or small diameter thereof to the bottom Specification of Letters Patent.

turning with the rod in case it is desired tounscrew the rod to remove it or to shorten the rod relative to the anchor for taking slack out of the guy wire.

hen it is desired to use one of my improved guy anchors all that is necessary is to bore a hole 11 in the ground of slightly larger diameter than the anchor, place the anchor on the rod in the position shown in Fig. l and drop it to the bottom of the hole 11 as shown in Fig. 2. Preferably a small quantity of broken stone or brick 12 is then placed over the anchor and well tamped. The hole is then filled with earth 13 level with the surface of the ground. Strain may then be applied to the guy wire 14, and it is obvious that as the upward pull or strain is thus applied to the anchor it wedges itself firmly in the ground or stone covering the anchor and the stone which are tamped tightly in position above the anchor will become partly embedded in the adjacent wall of the hole 11 so that a double taper ing wedge between the stone and the an chor will be effected and form a practically non-pull-out anchor.

The cone-shaped body illustrated herein is the most eflicient because it wedges outwardly in every radial direction, and the continuous annular corrugations provided around it are deemed to be the most efficient resistive engaging means to be pro-.

vided on the conical surface for the same reason. However, my invention is capable of considerable modification without departure from the scope or spirit thereof; and I do not wish to be understood as being limited to the precise illustration and description herein set forth, but

What I claim as new and desire to secure by Letters Patent is:

1. Anchoring means for guy wires or the like comprising a relatively large member adapted to be inserted into a suitable hole and having a tapering portion, and free relatively small but distinct bodies adapted to individually and automatically adjust themselves, said hole, member, and bodies being of a size and proportion relative to each other to effect a wedging action between said tapering portion and the wall of the hole to bind said member against withdrawal from the hole.

2. The combination with a base from which a guy wire or the like may be anchored, said base being provided with a suitable hole bordered by a wall of substan tial depth, of anchoring means comprising a member adapted to be seated in said hole and having a tapering portion, and free independently adjustable hard wedging bodies of a diameter greater than the space he tween the wider portion of said member and said wall and interposed between said member and wall, said hole, member and bodies being of a size and proportion relative to suitable hole bordered by a wall of sub stantial depth, of anchoring means comprising a member adapted to be seated in said hole and having a tapering portion, and free, independently adjustable hard wedging bodies of varying sizes of a diameter greater than the space between the wider portion of said member and said wall and interposed between said member and wall, said hole, member and bodies being of a size and proportion relative to each other to effect a wedging action between said tapering portion and the wall of the hole and binding said member against withdrawal from the hole.

4:. Anchoring means for guy wires or the like, comprising a member adapted to be inserted in a suitable hole and having a grooved upwardly tapering portion, the upper surface of the grooves tending in a downward and outward direction.
